IMPROVEMENT IN WOOD-BENDING MACHINES.

Specification forming part of Letters Patent No. 58,873, dated October 16, 1866.

To all whom it may concern:

Be it known that I, CHARLES MoYEn, J r., of Coopersburg, in the county of Lehigh and State of Pennsylvania, have invented a new and Improved Machine for Bending Wood; and I do hereby declare that the following is a full, clea-r, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot this specification, in which- Figure l represents a longitudinal vertical section of this invent-ion. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate like parts. y

This invention relates to amachine which is particularly intended for bending sleigh-runners, but which can also be used for bending ,strips of wood for other purposes. The strip to be bent is secured to a former by means of a ileXible metal strap, and said strap is provided with a link, through which the end of the strip ot' wood is passed, so that the same can be conveniently bent to the required form without orerstrainin g the strap and -with coinparatively little power.

A represents the former, which is made of wood or any other suitable material, and which may be secured in a suitable frame, B. Said former is made to correspond to the shape of the sleigh-runners to be produced, and that end ot' the former on which the goose-necks of the sleigh-runners are to be formed is provided with a round bar, a, which is secured in two brackets, I), secured to the opposite sides of the former, leaving room enough between the upper surface of the former and the lower surface ot the round bar or roller a to admit the strip of wood to be bent and the strap C, which is used in bending the wood. Said strap is made of sheet-steel, or other suitable flexible material; and when the saine is to be used in bending a strip of wood, said strip is placed between the flexible strap C and the surface of the former A, and both are secured to the former by a hook, c, at the end, and by a wedge, d, in the middle.

That end of the strip of wood which is intended to produce the goose-neck of t-he sleighrunner is passed through the space between the roller a and the former A, and in order to be able to keep the flexible strap C on the outside of the strip of wood, said strap is provided with an open link, o, through which the strip of wood is passed, as clearly shown in Fig. l of the drawings.

A hand-lever, D, which is hinged to the ends of the roller a, serres to force the strip of wood, together with the flexible strapG, round the roller a, as shown in the drawings, and when this operation has been accomplished the runner is ready.

It will be noticed that without the link e in the iieXible strap it would not be possible to keep the strip ot wood between the former and the iiexible strap in all those cases where the article to be produced has a shape somewhat similar to a sleigh-runner, or wherever any part of said article returns in a direction opposite to that in which the main part ot'said article extends, and in bending such articles it has heretofore been very difficult to produce the required shape. Vith my machine this operation is rendered comparatively simple and easy, and sleigh-runners, or other articles ofasimilar shape, can be bent with the greatest ease and facility.

What I claimv as new, and desire to secure by Letters Patent, is-

The link e in the flexible strap C, to operate in combination with the former A and roller a, or their equivalents, substantially as and for the purpose described.
